How Many RGB LED Strip per Power Supply? 

Thanks so much for this video. I spent like four hours trying to understand all this and you explained it so clearly!

How do you get 350w from multiplying 48 x 6? and how is that 75% of 400?

Wouldn't 75% be 300 watts instead of 350 watts? This video does explain well other than the stated safe wattage usage.

Thanks for prompt reply.

If i were to connect in series, but at a distance apart ... do you have the supported "length" configuration? For example, my setup is .... RGB strip x 2 (total of 30ft) RGB strip x 3 (total of 45ft). Basically i want to know is, if i put the power supply in the middle, how many strips each direction "in series" can it be supported with no voltage drop. (Also taking into consideration if i need to have a gap in between 2 RGB strips). ---> This setup is for outdoor X-mas lighting and hence not continuous...... Also, is this also valid for Technicolor pixel strings?

you need to show amps to watts conversion because a lot of the power supplies are rated in amps and that confuses some people

Hello +propfella, since we were not allowed to reply to your comment about our video directly, we thought we would post our reply to your comment here. Your Comment: propfella 8 hours ago Back to school for you mate. 75% of 400 watts is 300, not 350. ... 80% isn't pushing a 400 watt PSU, unless it's poorly designed of course. If the strips aren't working at maximum output continuously the use of more LEDs would be OK. As long as the temperature of the PSU doesn't get too hot, I'd be happy to use 7 strips. I've noticed in your videos you seem to tell viewers your LEDs etc are superior to others available. Aren't you simply a reseller of Chinese stock ?

How many Amps and Watts do i need on a power supply for a 5050 RGB 15m? It sais 5x12w for every 5m.

Hello. im interested in buying 20x LED strips, but i wanted like in the movie all connected INTO ONE CONTROLER. Is that possible? and whom i should contact?

I want to connect 3 5050 rgb led strips, would the voltage on the power supply have to be greater than 36 volts?

Thanks for the info in a very clear manner. As you mentioned the number 1 enemy of power supplies and LED's is Heat and here in AZ we have an abundance of that... LOL. We have been doing tons of installs for custom LED work ( along with Carbon fiber vinyl wrap, not sure why but they go together well) and when it is common to hit 120 degrees in the shade I have the guys use the 1/3 rule. Same thing except instead of 75% usage of max wattage we do 66%. So,in the same example I would do five strips hitting about 61% of the max wattage. I'm thinking we are starting 20% behind most everyone else before we even solder out first connection... Better safe than to see roasted components. My 2 cents if its worth anything. Thanks again for the great video!!

Informative video thanks. Question: now I know how to calculate the max strips per psu, how do I wire the strips? I've heard that they should always be wired in parallel as when wired in series it can overload the strip and lead to failure. Is this right? Thanks again.

which led strips should I use for promoting ads for a led hoarding? and what other parts would I need to make a whole led hoarding. For eg:- which video / photo controller, which power supply etc

what is sd strip and dd strips? and how long are the stipes that you are talking abouth? one more thing i like to put some led in my living room. the dimension of the room is 8m (26ft) long and 4m (13ft) wide. so in total i will need 24m (78ft) of rgb 50-50 stripes. can i use single power supply in my case?

I don't know nothing about these led strips but I guess I can go with the dual-density stripped and how many feet of line of lighting is that for a 400 watt power supply I don't know anything about this I know LED lighting but nothing with this trip so I'm trying to learn so I'm trying to say I need about 600 feet of lighting so what's the best way to go on about that I want light changing I want motion and not want to run at all on one Outlet

I hope I didn't miss this being explained elsewhere but how can I tell if I have a Dual or Single density strip? Is there a sure fire way of knowing w/out going back to the manufacturer? Over the years i have purchased different lights from different vendors and they get mixed together etc. Thanks!

I have a 12 voltz with 15 Amps power supply... how many Strip Led lights does it can light up? and do I still need to put some resistor on it? pls help thanks...

Hello! I have purchase Warm white 5x5M of 3528 SMD 600 LED waterproof strip. I wanted to connect each of them for me to have a 25M long strip. can you please advise how much power supply do i need to use. Thanks!

7 x 48 W is about 350 W, not 6 x 48 ???

So in the video it recommends a maximum of 6 strips for DDS and would make the assumptions of 12 SDS, but on your power supply there is only space for 3 +/- connections, Do you just wire 2 strips to each for DDS and 4 strips to each for SDS?

Can I solder three 5 meter RGB stirps together and will it work, Or will there be peoblems

I am in a situation to have 5/ 5M RGB Double raw lede strip lights together. But each 5M pieces are in a distance of 10 feet away.. I want all the strip lights change the colours at the same time. Please help me with the correct way to do it. Thanks in advance

You didn't mention how long these light strips are. I'm assuming 5m. Also these strips would be wired in a home run configuration and not daisy chained together, correct?

The single color led strips runs at 3 watts a meter. It needs 5 watts a meter to run for a power supply. I made a video also and went over that.

+Class E Vapes Hello, the specs on that are 24 watts each, a 200w power supply should do the trick. Please see our power supplies. sirs-e.com/product-category/led-lighting/led-strip-lights/led-power-supplies/power-supplies-led-power-supplies/

Hi. Is this calculation only for serial wiring or does it work with parallel circuit too?

what happens to those leds at the beginning of the stripe? will they survive the power coming through?

I have 20meters (5m x 4) Led strips ( 12v 2A each) This means i have to get a Power Supply above 48W? I am planing on combining all of the strips together to form a 20m. Any recommendations ??

Hi, can you make any waterproof led strip and use it for a signal light on a car or truck and for outside of the front headlights? Ty

The total wattage is 400w but there is 3negative and 3 positive outs. So 400 should be divided by 3 and we can hook up only 2 led Strips per power out?

My project will be wiring 5 M role of RGB loom into my outside exposed weather decking. What type of RGB controler do I use for this job? the looms connections are under the decking

i have the dream magic 6803 led light strips , i have a 12v 50A 600 watt power supply. how would i hook up lets say 10 5M rolls of lights up to the power supply and controller. can i run them all together end to end ?

So If I wanted to run 2 16ft led strips together and the power output on each strip is 0.2w/led 60w/300leds which power supply would I need cause the power supply that came with the lights is "12v DC 5000mA" and the max wattage is 60w. So Im guessing with the provided power adapter it wont have enough wattage to run both 16ft strips together.

Greetings .. I have two 24v strips .. can I hook both up on one 300w driver and one dimmer ?

Hey :) and what about series/parallel installation of the strips ????

What ampere power supply is required for 1m 5050 RGB 60Led /meter , 5m and 21meter . Correct me if i am wrong, 1A/meter is required for RGB 5050 60LED/meter , so for 5meter it will require 5A*12v=60W power supply ? For 21meter 5050 it will be 252W power Supply ? What about power consumption of the IR controller . On most chinese sites i see power controllers that are rate 6A,12A,24A,36A . So my next question is what ampere rating IR controller should be bought for a 21m RG 5050 60L/m ? What we adding the power consumption of IR controller (6A/12/24/36) to power supply load calculation?

So, what if you get the power from the house outlet nearby and then an extension cold attached to it? How many watts would that be total and how many strips? Thanks bud! Hope you reply back.

helpful,thank you

When you are using that many strips don't you need a RGB amplifier of some kind because some of the strips after 10m will get dim?

I have a 5m 300 led 5050, can I use a dell laptop power supply let's say 19v 3.4 a ???

if i use 36 watt led strip by 4 = 144 watt, refer to your guidance ideally i need to choose 180 watt power supply.....But for availability reason is it ok if i use 360 watt power supply ?

Are you connecting them in parallel or series!???

Hello, to run the SD led for 400W psu, best is to use 6 strips, isn't? May I know "strip" refer to 5-metre per strip?

Van I plus The stript directly on a 12 Volt car batterie ?

Nice video. Still have a doubt. Let's say I want to power some RGB 5050 leds strips that add up to 6A (12v). and I have the option of buying a 6A 12v power supply transformer, or a 10A 12v. And, I'm using a controller (the classic white one that all vendors on ebay or aliexpress sell) that in the specs it says "OUTPUT 6A". I assume that if I'm using more than 6A power supply, it will be "useless" since the power will go first to the controller and it will limit the intensity (A) to 6A, right? So buying the 10A will be useless unless I buy amplifiers? Am I correct? Thanks

HI, Thanks for the video, i am based out of philippines and planning to install LED in my 24 hours store. i have just ordered 1 5M 5630 chipset and looking at the W it says 36 W . does it mean its 36WATT/5 METER = 7.2 Watt/Meter ? 36 WATT/METER doesnt sound right to me else it will be more expensive as compare to regular light isnt? Also does 48 W led take some amount of electricity as 48 W of fluorescent tube? if yes then how can anyone save electricity by switching to LED? sorry to trouble you with my questions

So if I have a DC 5V 60A 300W PSU and two strips of LEDs (WS2812B ) 5V would this blow my lights?

So if i was to run 4 Rolls, Would I just run each end of the strip to the power supply? or can I run 10M straight x2?

Double density = 48W ? Does anyone know what they are talking about ? He mentions 5050 and 3528 strips. A 60 led / m, 5050 strip is 14.4 x 5m = 72watts; 30 leds /m = 36watts A 60 led / m 3528 strip is 4.8 x 5m = 24watts; 30 leds /m = 12watts Where is he getting 48 watts from ? The most common, 60 leds / m, 5050 at 72 watts per 5 meters x 6 (as he suggested) would draw 432 Watts ! So much for the 400 watt power supply !?!

How do you control more than 1 5M roll of RGB or RGBW led strips? The seller I asked on eBay has no idea. I'm looking to use 5 rolls for the front room project in my place as I have a 450W computer PS already, I would like to use the RGBW so it can be my main lighting. Thank you very much

ALL of the LEDs aren't on all the time . Did you figure that into your calculations?

Question- I'm new at trying to do this and at the risk of sounding like a Idiot when you are saying strips what do you mean ( 1 roll or what) Or is it peices of a roll or a certain number of light's.

I bought a LED strip and I want to cut off some from the strip to use in different places. How would I do this? Would I need to buy more power supplies?

so if I wanted to connect 2 stripe together I would need 100 w 12v 5a?

Hi Can you give me need of power /m ?! As im using about2.5-3m rgb strips,not a full roll(5m) Thanks

Will a 10A power supply damage a 5M 5050 LED Strip and Controller?

Can i power 2x5M RGB Strip 12V 5A Power Adapter without loosing brightness or else?

I'm doing 4 8' sections (double row per section), with a 725watt psu. Do I need to connect each section to its own yellow and black on the power supply?

if i have 10m 5050 led strips and a rf music controller, what power supply do i need? :P

Prices nuts! I'm willing to pay more for quality & good service but your prices are crazy. Buy 5 sets from China With money left over. Assume two are crap still better.

Last time I checked 48W*6=nearly 300W not 350W. No sweat

Thanks for your quick reply, so will UL Listed MeanWell LED Power Supply 60 Watts 12 Volts 90-264 Waterproof be right for me?

How long is a strip?

I have a 5 mtr strip led, what power supply do I need? Please.

i will use 1 controller and 5 amplifier for 30m (5m each), is this the best way, or is there a better way of doing this? someguy on the chip forum helped me with it and told me this was the best way for long sustainability of the leds. i will order the pieces today or tomorrow, so if you would help me real quick, it would be a big thing for me right now.. the bad thing about this is, that i need to run cable to the strip and back to the amplifier/controller every time, this means around 100m 4x1,5 cable, which is not that cheap to be honest, thats my point.. a lot of people told me that running 5m 12v is the best way doing it, and not more ..

1300 watt how many led's can i run

how many lights on a strip?

So a "400 watt" power supply is actually a 300 watt with a service factor of 1.25? Why isn't it advertised correctly? if it can only safely service at 300 watts with a maximum of 25 % over before it blows, its only a 300 watt. that's how it should be listed. Are all marketing people trained to twist truths to gain sales, or just your company? Nah, I know its not just you, just giving you a hard time, but in reality I don't know that i can trust you now.

so if I were to have 4 RGB strips. one power supply of 400w, would light them all up

Hi! This was an interesting watch, and I feel almost ready to re-revisit my LED wiring mission (which I had to abandon before as I had serious power issues). I am looking to wire eight separate strips of RGB 5050 strip lighting around different areas of my room. I tried this in series but realised I didn't have enough power in the circuit, and loose connections between the strips was a nightmare too so I had to give up. Each LED strip I intend to use will be around 1m long. If I want to wire these in parallel, and each strip has the brightest 60 LEDs per metre, how big a power supply will I need, please? Can I wire 8 x 1metre strips with one power supply safely? Thank you!

"you could get thermal issues, and you know a bunch of other issues" Yeah - like Fire right? Say it! SAAAAYY IIITTTT!!! Good video though dude - thanks

350 is definitely not 75% of 400.

Too simple. There are volts and there are amps also.

He can't count very well can he xD
